An airplane maintains a speed of 693 km/h relative to the air it is flying through as it makes a trip to a city 766 km away to the north.
(a) What time interval is required for the trip if the plane flies through a headwind blowing at 36.9 km/h toward the south? Answer - 1.1675
(b) What time interval is required if there is a tailwind with the same speed? answer - 1.049
(c) What time interval is required if there is a crosswind blowing at 36.9 km/h to the east relative to the ground? answer - 1.105
I managed to get all the right answers, however I'm not sure what I did to do this and would like an explanation on it as well. Thanks!
